CR 45-7-2 A-F-A-V-HQQV
Note! Product picture may differ from actual product
Product No.: 96122833
Vertical, multistage centrifugal pump with suction and discharge ports on same the level (in-line)
enabling installation in a horizontal one-pipe system. The pump head and base are in cast iron – all
other wetted parts are in stainless steel. A cartridge shaft seal ensures high reliability, safe handling
and easy service and access. Power transmission is via a split coupling. Pipework connection is via
DIN flanges.
The pump is fitted with a 3-phase, fan-cooled asynchronous motor.
Further product details
Steel, cast iron and aluminium components have an epoxy-based coating made in a cathodic
electro-deposition (CED) process. CED is a high-quality dip-painting process where an electrical
field around the products ensures deposition of paint particles as a thin, well-controlled layer on the
surface. An integral part of the process is a pretreatment. The entire process consists of these
elements:
1) Alkaline-based cleaning.
2) Zinc phosphating.
3) Cathodic electro-deposition.
4) Curing to a dry film thickness 18-22 my m.
The colour code for the finished product is NCS 9000/RAL 9005.
Pump
A long split coupling connects the pump and motor shaft. It is enclosed in the motor stool by means
of two coupling guards. The long coupling makes it possible to replace the shaft seal without
removing the motor from the pump.
The motor stool connects the pump head and motor. The pump head has a combined 1/2" priming
plug and air vent screw.

The pump is fitted with a balanced O-ring seal unit with rigid torque transmission system. This seal type is
assembled in a cartridge unit which makes replacement safe and easy. Due to the balancing, this seal type is
suitable for high-pressure applications. The cartridge construction also protects the pump shaft from possible
wear from a dynamic O-ring between pump shaft and shaft seal.
Primary seal:
- Rotating seal ring material: Silicon carbide (SiC)
- Stationary seat material: Silicon carbide (SiC)
This material pairing is used where higher corrosion resistance is required. The high hardness of
this material pairing offers good resistance against abrasive particles.
Secondary seal material: FKM (fluorocarbon rubber)
FKM has excellent resistance to oils and chemicals. Above 90 °C, FKM should only be used in
media without water.
The shaft seal is retained in the pump head by a cover and screws. It can be replaced without
removing the motor.
The chambers and impellers are made of stainless steel sheet. The chambers are provided with a
PTFE neck ring offering improved sealing and high efficiency. The impellers have smooth surface,
and the shape of the blades ensure a high efficiency.
The base is made of cast iron. Both the suction and the discharge side of the base have two
pressure gauge tappings. The pump is secured to the foundation by four bolts through the base
plate. The flanges are fastened to the base by means of locking rings.
Motor
The motor is a totally enclosed, fan-cooled motor with principal dimensions to IEC and DIN
standards. The motor is flange-mounted with free-hole flange (FF).
Motor mounting designation in accordance with IEC 60034-7: IM B 5 (Code I) / IM 3001 (Code II).
Electrical tolerances comply with IEC 60034.
The motor efficiency is classified as IE3 in accordance with IEC 60034-30.

The motor has thermistors (PTC sensors) in the windings in accordance with DIN 44081/DIN 44082. The
protection reacts to both slow- and quick-rising temperatures, e.g. constant overload and stalled conditions.
Thermal switches must be connected to an external control circuit in a way which ensures that the
automatic reset cannot cause accidents. The motors must be connected to a motor-protective circuit
breaker according to local regulations.
The motor can be connected to a variable speed drive for adjustment of pump performance to any
duty point. Grundfos CUE offers a range of variable speed drives. Please find more information in
Win-/WebCAPS.
